Like I’ve previously said, the Apple iPhone is gaining an abundance of applications available from the Apple iTunes App Store, and Intomobile has come across iBone for the iPhone by Spoonjack.

What iBone for the iPhone basically is is apparently called “Pocket Trombone for iPhone and iPod Touch.” It’s an app that lets the iPhoner play along with music from their iTunes library and also songs within the iBone songbook.

The basics go like this, slide your finger to adjust pitch, blow or touch the screen to make a sound, and raise and lower the bell to up and down the volume. iBone is a fun app for the music minded iPhoner and costs $2.99.
